Offgrid camping and powering inverter?

Is there a way to use the campers inverter offgrid? I would love to watch tv or power my blender without having to start the generator everytime. Plus some places dont allow generators. I have soloar panels and batteries ill eventually install... someday :-)

Suggestions?

Are you sure you have an inverter? Most units do not have one from the factory but all of them have a converter (which converts 115 Volts AC from your house or rv park) to the 12 Volts DC that most items in a camper use such as your lights water pump LP gas detector etc. You may have a 12 volt outlet somewhere in your trailer around the tv possibly which you could plug a small inverter into but the wiring is usually very light to these and it will limit the power the inverter can produce. I would suggest a pure sine wave inverter hard wired to your battery with as short as possible cables to the inverter from the battery.

A-frames don't have inverters.
It has a CONverter. All RVs come with converters. Few come with INverters.
You'd have to install one.

x2 that most factory RVs will not have an inverter, only a converter.

A modern LCD television really does not take much power. YMMV but I have found a cheap modified square wave 400W inverter plugged into the cigarette lighter power plug drives my Furrion flat panel TV just fine.

Just beware of the power consumption which must balance power availability. If your TV consumes 100W... that is 8.3A being pulled from your battery. By way of comparison your heater fan probably pulls half that, so this is a high load for a 12V battery. Especially since it is a constant long duration load. A dead battery can result quicker than you might want unless you offset that consumption with some production.

You will need a big inverter to run most home blenders. To draw that much current off one deep cycle battery may do some damage. Deep cycles are made for deep discharge at the expense of fast discharge. Starting batteries are made for fast discharge but can't be taken to a low level of charge very often.

Most TVs have a fairly low draw, so for that alone you could find an inverter that matches the wattage. Or find a 12 Volt TV.

Yep and that blender will deplete the batteries.
I'd have two 6v golf cart batteries if I was going to use that heavy a power draw.

My TV is 12 volt 24" Insignia and pulls 3 amps. I run TV off of trailer battery however my Blender pulls over 40 amps at 12 volts so as others say it would take a large inverter to handle that so no blender for me.. I do use my 750 watt inverter to power an electric coffeemaker. It pulls around 6 amps at 12 volts and I carry a second battery to run inverter.

I think you may need one of these:

The Daiquiri Whacker Gas Powered Portable Blender

Haha yes thise gas power blenders are awesome. Someone always had one after everyone was done racing. Good times.

Thank you for correcting me on the inverter. After yall said its a converter everything makes sense. I will have to do some thinking on the setup.

The tvs do not use much power anymore. We run one at the ranch and it barly drains the battery.

I have some thinking to do. Thanks everyone!
